Randomized Controlled Trial Multicenter Study Clinical TrialPatterns of failure following loco-regional radiotherapy in the treatment of limited stage small cell lung cancer.
The probability of treatment resistant cells developing in a tumor, such as small cell lung cancer (SCLC) which has a rapid cell cycle time, is a function of the number of tumor cells present and of time. Theoretically, the development of resistance to chemotherapy and radiotherapy should be minimized by using all treatment modalities early in the treatment program. ⋯ We conclude that early administration of locoregional radiotherapy in a combined modality treatment is superior to late consolidative locoregional radiotherapy in limited small cell lung cancer.

Randomized Controlled Trial Comparative Study Clinical TrialLow dose rate vs. high dose rate brachytherapy in the treatment of carcinoma of the uterine cervix: a clinical trial.
This study is a prospective randomized clinical trial undertaken at our center to compare low dose rate versus high dose rate intracavitary brachytherapy for the treatment of carcinoma uterine cervix. ⋯ Thus high dose rate intracavitary brachytherapy is an equally good alternative to conventional low dose rate brachytherapy in the treatment of carcinoma of the uterine cervix.
